OF ST. LOUIS, MISSOURI tJAR-UNDERFRAME.

Specification of Letters Patent.

Patented April 27, 1909.

Application filed November 2, 1903. Serial No. 460,710.

To all whom it may concern:

Be it known that I, CLARENCE H. How- ARD, a citizen of the United States, residing at St. Louis, in the invented a new and (.ar-Underframes, of specification.

My invention relates to a metallic car underframe, particularly applicable. to a fourwheeled caboose car, and has for its object to provide. a strong and rigid underframe haying its component members disposed to the best advantage for sustaining the superineumbent load and resisting shock.

It consists in features of novelty as hereinafter described and claimed, reference being bad to thea ctunpriiiying drawing forming part of this .gpeeifiration, where-on, T

Figure 1, is a. top plan View of my imroved metallic under-frame as applied to a four-wheeled caboose ear, and having its end portions arranged either with, or Without the side stepppenings, as shown to the right and left res n=-:-tively, of the figure; Fig. 2,11 side el(.=vation thereof; Fig. 3, a vertical longitudinal section tl'irough the underframe (broken away) on line 3, 3, in Fig. 1; Fig. 4, a. vertical transversesection thereof on line 4, 4, in Fig. 1, omitting the draft-gear, and Fig. 5, a. view similar to Fig. 4, on line 5, 5, in Fig. 1.

Like letters and numerals of reference denote like parts in all the figures.

(L represents my improved metallic underframe as applied to a. four-wheeled caboose car and composed preferably of cast steel integral throughout. The. underframe a comprises mainly, two opposite longitudinal members or wheel-pieces 1, which in the present ease are channel-shaped in cross sec tion and adapted laterally at 1 for the attachmcnt thereto of the axle-box pedestals (not shown).

The heel-pieces IV are united together, preferab y in the middle, by a transverselsha )ed member 2 (or by a similar member at each side of and equidistant from the middle as the case may be), and at each end by :1. preferably, transverse. channel-she. ed member 3 which is adapted at its midd portion for the application thereto of a suitable draft-gear b, the transverse members 3 being united to each other thercat by e longitudiuseful Improvement in which the following is a nal preferably I-shaped middle or bufling member 4 which intersects the middle transverse member (or members) 2.

'In the present case the end and middle State of Missouri, have transverse members 2 and 3 are extended a suitable distance beyond, or overhang, each I wheel-piece 1 and are united together at their outer ends by a preferably, longitudinallshaped member 5, and at a suitable distance l from and parallel to each transverse member 5 3, is a transverse preferably, box-shaped end I sill or buflenbeam 6 which, as seen to the right in Fig. 1, is united to the corres ending i transverse. member 3 by a series of ongitw dinal preferably L-shaped members 7 suitably arranged for the attachment thereto of the platform (not shown) and to form the openings 8 for the side steps (not shown), of the car, the other end portion of the underframe (t being in this case similarly constructed; while in the case of a caboose car used without the ste openings 8, the transverse end sills or bulibr-b'eams 6, as seen to the left in Fig. 1, are respectively, united to the corres ending transverse member 3 bye serics o' outer and inner longitudinal preferably, L-sha id members 9, 9, the outer members 9 being preferably aliued to and forming continuations of the corresponding longitudinal members 1 and 5 as shown. On the underside of the longitudinal members or wheel-pieces 1 and integral therewith are preferably formed, adjacent to the pedestal planing faces 1, the dependent spring-brackets 10, and the brake-hanger brackets 11.

The great advantage of the above construction is, that the long continuous middle longitudinal bulling" member 4, combined with the adjacent members and end sills in connection therewith, presents a very rigid resistance to the shocks to which the caboose car is subjected in the case of long and heavy trains when it becomes necessary in many places to use one or more locomotives" in the rcztr of the train as pushers in ascending heavy grades. ordinary truck-frame and car underframe as it were in one piece greater simplicity of construction is effected.

What I claim as my invention and desire to secure by Letters Patent is '1. A car'underframeof the class described, comprising two opposite longitudinal wheelpieces adapted for the attachment thereto of the axle-box pedestals, a transverse member uniting the Wl10( lpieces together at each member, longitudinal members uniting the said member and end sill together, and a. transverse member uniting the wheel-pieces Moreover, by combining the end thereof; an'end sillparallel to the said together intermediate to their ends, sub-' suitable draft-"ear, an end sill parallel to the said member, ongitudinal members unitingthe said member and end sill together, and a transverse member uniting the wheel-pieces together intermediate to their ends, substantially as described.

3. A car underframe of the class described, comprising two opposite longitudinal wheelpieces, a transverse member uniting the wheel-pieces to ether at each end thereof, an end sill parallel to the said member, longi tudinal members uniting the said member and end sill together, a longitudinal member uniting the said transverse members to ether intermediate to their junction wit the wheel-pieces, and a transverse member intersecting'the said longitudinal member and uniting the wheel-pieces together intermeas described.

4. A car underframe of the c ass described, comprising two opposite longitudinal wheelpieces, a transverse member uniting and extending beyond the wheelieces atv each end thereof, an end sill paral el to the said member, longitudinal members uniting the said member and end sill together, a transverse member uniting and extending beyond the wheel-pieces intermediate to their ends, and a longitudinal member parallel to the wheel-pieces and uniting the said transverse members together on the outside of each wheel-piece, substantiall as described.

5. 'A car underframe o the class described, comprising two opposite longitudinal wheelpieces, a transverse member uniting and extending beyond the wh'eel- ,ieces at each end thereof, an end sill paral el to the said members, longitudinal members uniting the said member and end sill together, a longitudinal'member uniting the said transverse memberstogether intermediate to their junction with the wheel-pieces, and a longitudi nal member parallel to the wheel-pieces and uniting the said transverse members together on the outside of each wheel-piece, substantially as described. 7
